LOG: [compiler-rt] Replace assignment w/.set directive (#107667)

These assignment statements are rejected by `llvm-mc --triple=hexagon`,
likely because the syntax so strongly resembles hexagon asm mnemonics.

The statements were being normalized by llvm-mc into `.set` directives
for most architectures, so I assume that this change is a portable one.
